SS210 Schottky Diode 100V 2A DO-214AA Equivalent & Substitute Parts

Part Overview

The SS210 is an active-status Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100V DC reverse voltage and 2A average rectified current in a surface-mount DO-214AA (SMB) package. This component is commonly used in power supply circuits, voltage regulation applications, and reverse polarity protection where fast recovery characteristics and low forward voltage drop are required.

Equivalent and substitute parts are identified based on matching or exceeding the electrical performance parameters while maintaining compatibility with the DO-214AA surface-mount package footprint. Substitutes are categorized by parametric equivalence, automotive qualification, and current rating variations to support design flexibility and supply chain alternatives.

Substitute Part Grouping Explanation

Substitute parts for the SS210 are classified into three functional categories based on electrical parameter alignment and application suitability:

Parametric Equivalent (Direct Replacement) Parts matching all critical electrical specifications: 100V reverse voltage rating, 2A average rectified current, fast recovery characteristics, and DO-214AA package compatibility. These parts are interchangeable without circuit redesign.

Current Rating Variants (1A and 3A/5A) Parts with identical voltage ratings and package but different current ratings. 1A variants (B1100BQ-13-F, CDBB1100-HF, SK110-LTP) are suitable for lower-current applications. 3A and 5A variants (CDBB3100-HF, CDBB5100-HF) support higher-current designs where the SS210's 2A rating is insufficient.

Manufacturer Alternatives Parts from alternative manufacturers (Diodes Incorporated, Comchip Technology, Fairchild Semiconductor, Micro Commercial Co) offering equivalent or superior electrical performance in the same package family, enabling supply chain diversification and cost optimization.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent)

SS210H (Taiwan Semiconductor Corporation) is the primary parametric equivalent, offering identical electrical specifications with AEC-Q101 automotive qualification. This part is suitable for applications requiring automotive-grade reliability and traceability.

B2100Q-13-F (Diodes Incorporated) provides equivalent 2A current rating with lower reverse leakage (7 µA vs. 100 µA) and AEC-Q101 qualification. The reduced forward voltage drop (790 mV vs. 850 mV @ 2A) results in lower power dissipation, beneficial for thermal-constrained designs.

B2100-13-F (Diodes Incorporated) offers the same electrical performance as B2100Q-13-F without automotive qualification, suitable for commercial-grade applications.

Current Rating Variants

For applications requiring lower current capacity, B1100BQ-13-F, CDBB1100-HF, and SK110-LTP provide 1A ratings with 100V voltage compatibility. These parts reduce component cost and thermal load in lower-current circuits.

For applications requiring higher current capacity, CDBB3100-HF (3A) and CDBB5100-HF (5A) maintain 100V voltage rating and DO-214AA package compatibility. CDBB5100-HF offers the lowest forward voltage drop (700 mV @ 5A) among all listed alternatives.

Compliance and Certification

Parts with AEC-Q101 qualification (SS210H, B1100BQ-13-F, B2100Q-13-F) are required for automotive applications. All listed parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes.

Temperature Range Considerations

SS210 operates across -55°C to 150°C. B2100-13-F and B2100Q-13-F extend the lower temperature limit to -65°C. CDBB3100-HF has a restricted upper temperature limit (-40°C to 70°C), unsuitable for high-temperature applications. CDBB5100-HF operates -55°C to 125°C, acceptable for most industrial applications but with reduced upper temperature margin.

Frequently Asked Questions (FAQ)

Q: Can SS210H be used as a direct replacement for SS210?

A: Yes. SS210H is a parametric equivalent with identical electrical specifications (100V, 2A, 850 mV forward voltage, fast recovery). The primary difference is AEC-Q101 automotive qualification and packaging format (Tape & Reel vs. Cut Tape). Both parts are pin-compatible in DO-214AA packages and require no circuit modifications.

Q: What is the difference between B2100-13-F and B2100Q-13-F?

A: Both parts have identical electrical specifications (100V, 2A, 790 mV forward voltage, 7 µA reverse leakage). B2100Q-13-F includes AEC-Q101 automotive qualification; B2100-13-F does not. Selection depends on application requirements. B2100Q-13-F is mandatory for automotive designs; B2100-13-F is suitable for commercial applications.

Q: Can I use a 1A-rated diode (B1100BQ-13-F) in place of the 2A SS210?

A: No. The 1A current rating is insufficient for circuits designed for 2A operation. Using an undersized component results in excessive power dissipation, thermal stress, and potential device failure. Use 1A variants only in circuits with confirmed maximum current ≤ 1A.

Q: Can I use a 3A or 5A variant instead of the 2A SS210?

A: Yes, for current capacity. CDBB3100-HF (3A) and CDBB5100-HF (5A) are electrically compatible with higher current margins. However, verify operating temperature range compatibility. CDBB3100-HF is limited to -40°C to 70°C, unsuitable for wide-temperature applications. CDBB5100-HF operates -55°C to 125°C, acceptable for most industrial use.

Q: What is the significance of forward voltage drop differences (850 mV vs. 790 mV)?

A: Forward voltage drop directly affects power dissipation and thermal performance. Lower forward voltage (B2100 series at 790 mV vs. SS210 at 850 mV) reduces heat generation by approximately 7% at 2A operation. In thermally constrained designs, lower forward voltage improves reliability and extends component life.

Q: Are all listed parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting standard PCB assembly and storage requirements without special handling.

Q: What packaging formats are available?

A: SS210 is supplied in Cut Tape (CT) & Digi-Reel format. SS210H, B1100BQ-13-F, B2100Q-13-F, and all Comchip CDBB variants are supplied in Tape & Reel (TR) format. S210 is supplied in Bulk. Verify packaging compatibility with assembly equipment and procurement requirements before selection.

Q: Can I substitute parts from different manufacturers in the same circuit?

A: Yes, provided electrical specifications match or exceed design requirements. All listed parts maintain DO-214AA package compatibility and fast recovery Schottky technology. Verify forward voltage drop, reverse leakage, and temperature range alignment with circuit design margins before implementation.

Q: What is the difference between DO-214AA and SMB package designations?

A: DO-214AA and SMB refer to the same physical package. DO-214AA is the JEDEC designation; SMB is the industry common name. Both terms describe identical surface-mount packages with identical footprints and pin configurations.
